Giant brands like Apple and IBM have immense design systems that are broken down into video content and relatable use cases for designers to apply the wealth of information.

The incentive for building a design system is to align the foundations of a brand’s design language, streamline UX processes, and create a scalable UI language that allows designers to make better decisions and develop ideas faster.

Here is your guide to some of the best public design systems—with inspiration, resources, and lessons learned along the way.

Atlassian

Atlassian’s design system is about using personality to connect tools with people—or as they describe it, “practical with a wink.” It’s personal, peppy, and all about making a bold brand statement. “Dragon’s blood,” “cheezy blasters,” “hairy fairy,” “herky jerky,” and “sodium explosion” are all names of colors referenced in their secondary brand palette.

Accessibility is important to Atlassian and their design adheres to standard contrast ratios that ensure users with low vision can see and use their products. In essence, the Atlassian brand is optimistic and focused on being “human” over “humourous.” Read about their recent rebrand.

Shopify

Shopify’s design system is called Polaris. It’s a system that reflects Shopify’s global, immense presence. It’s about scalability and ease of use. With precision in their copy and design, Shopify is solely focused on the experience of their merchants.

It’s easy to see how Shopify helps businesses manage global complexity, with an experience that gives “even the most inexperienced entrepreneur the best chance to succeed.”

Accessibility and intentional design is paramount in Polaris. Scaling a business is like climbing a mountain, so their design decisions seek to make any user feel like they’re up the challenge.

IBM

With one of the most iconic design languages around, IBM presents an immense resource that includes data visualization, typography, animations, and information architecture.

IBM’s design is timeless, precise, and yet approachable. Their resources distill every design concept into a real example, cutting through the almost overwhelming knowledge bank to explain best practice applications.

Airbnb

Airbnb’s design system is promoted as “conversational,” laid out in an article by Airbnb Design Language System Lead Karri Saarinen. Saarinen points out that design systems exist to ensure they can manage chaos and create better products.

A global community like Airbnb needs a unified approach to design that’s clear and promotes efficiency through beautiful design.

The resulting design language is a coherent yet iconic identity that will continue to evolve with Airbnb’s global growth. By reflecting on lessons learned, Saarinen also leaves some advice for designers embarking on a design system project.

Microsoft

Microsoft’s design system involves sensory experiences like depth, light, motion, and materials. Their design manifesto is compelling, and describes building the future of design while our digital world is at a precipice.

MailChimp

MailChimp’s pattern library is a living, breathing guide for the MailChimp interface elements. It’s a resource for their team to view the “greatest hits collection of ideas” that MailChimp have adapted to build their platform.

While the pattern library is a valuable design learning tool, their content and tone guidelinesare where the MailChimp personality shines through. Their writing resources are a goldmine example of how UX writing informs and shapes the design of a product.

Trello

Trello’s design system is called Nachos. As their favorite snack, Nachos serves as a tasty resource with all the right ingredients for design success. Yes, the system is also built on food puns.

BuzzFeed

BuzzFeed’s CSS and component library is called Solid. Solid is presented as a “roadshow” of BuzzFeed design practices from across the web.

The fast-growing company needed a consistent design library, as new designers and product managers found themselves starting from scratch too often, and they had few approved design patterns to choose from.

Solid exists to bring engineers and designers close together for a better product, helping engineers influence design decisions, and placing designers in the code. In true BuzzFeed style you can read about Solid in the “WTF is Solid?” section.

Buffer

Buffer’s style guide is based on the principles of atomic design—the theory of small (atomic), independent parts working together to be apart of a larger structure. Since Buffer is famously a remote company with employees roaming the globe as digital nomads, this design concept is in line with their brand.

Their design system strives for consistency, clarity, and simplicity to maintain their product as an unobtrusive tool for managing content.

Apple

Apple’s design system collection is in-depth and interesting. Designers can watch video sessions and tutorials on crafting intuitive, forward-thinking experiences and find the latest resources on optimizing for iPhone X. These include designing for sound, writing the perfect push notification, and designing for a global audience.

With hours and hours in their video collection, a designer can get lost in Apple’s design inspiration. Apple also advocates designing for a global audience, with tips on marketing and accessibility measures that will differ across international markets.
